Over time, all SPL meters lose their calibration. The Galaxy Audio CM-C200 is a sound pressure level (SPL) meter calibrator. The CM-C200 meets IEC 60942 2003 Class 2 and ANSI S1.40-1984 standards. The CM-C200 can calibrate 1", 1/2" and 1/4" microphone capsules at 94dB and 114dB.  

The calibrator is designed to calibrate SPL Meters with a microphone diameter of 1/4", 1/2" and 1". The CM-C200 will work with any of the CheckMate SPL Meters and many other brands. The CM-C200 has a test tone at 1kHz at both 94dB and 114dB. The CM-C200 includes 2 adaptors a protective zipper pouch and manual.
